Begin with two static routes (one can have an better metric if you do not want load-balancing)
) and two nat statements. Once you are in the situation where you can shutdown either interface, clear nat translations, and things continue to work, you go for the second part (ip sla).
The initial example is:

the advanced one is:

Good luck!
Hope this helps, please rate post if it does!

Hello sun,
if you want to use PBR = policy based routing you need to apply it on the inside interface.
In fact, with your configuration you are checking if the source address is in the server address block or if it is in the user block.
Move the command ip policy route-map univer command under the inside interface
hope to help

That is not an easy configuration. Do you have enough expereince to read and interpret examples and adapt them to your needs ?
03-26-2008 08:45 AM
yes. I think that I would have enough experience what to adapt examples under the requirements

Hi.
In my network work next sheme.
traffic network 10.10.10.0/24 and 10.10.11.0/24 collect on 3750 and goto on 2821 with ip 10.10.4.1 and goto internet.
And if i move commad ip policy route map univer under interface with ip 10.10.4.1 it's not work.
As still it is possible to make distribution of the traffic between ISP? for network 10.10.10.0 --> ISP1 and network 10.10.11.0 --> ISP2
